Kylian Mbappe answered his critics in style as he netted his first La Liga goals to give Real Madrid a 2-0 win over Real Betis at the Santiago Bernabeu on Sunday which sends them second in the table.

Since scoring in the UEFA Super Cup against Atalanta, new signing Mbappe had failed to find the back of the net in Madrid's opening three games in La Liga, prompting criticism in the Spanish press.

Mbappe was made to wait for his goals as he squandered a series of chances, finally finding the back of the net in the 67th minute, sweeping the ball past the Betis goalkeeper with his left foot after a well-timed back-heel from Fede Valverde.

Eight minutes later the France captain added a second from the penalty spot and was cheered off the field when he was replaced by Luka Modric in the 84th minute.

The smile on Mbappe's face was in contrast to the concern that had been shown since scoring his first goal and winning his first trophy in Warsaw on August 14.

On Saturday, coach Carlo Ancelotti hit back at the criticism, insisting that his star recruit was settling in well.

"It's true that he hasn't scored but he's playing very well and has been very dangerous every time. I don't think he has any problems adapting," said Ancelotti, pointing instead to his team's lack of balance.

Madrid's 2-0 win takes them second in the table with eight points, four behind early leaders Barcelona who eviscerated Real Valladolid 7-0 on Saturday to make it four wins from four in La Liga under new coach Hansi Flick.

Atletico Madrid are third after a late victory in Bilbao on Saturday while Villarreal are fourth, both of them also on eight points.

Girona are fifth after picking up their second win of the season in Seville.

Ivan Martin put Girona ahead in the 41st minute with Abel Ruiz wrapping up a 2-0 win over Sevilla with a penalty in the 73rd minute.

Goals from Carlos Vicente and Luka Romero gave Alaves a 2-0 win over Las Palmas while Osasuna are in seventh after an exciting 3-2 win at home against Celta Vigo.

Ante Budimir teed up Flavien Boyomo to put the home side ahead after 21 minutes but the lead was short-lived as Borja Iglesias levelled for Celta.

A Carlos Dominguez own goal just before the break put Osasuna back in front with Abel Bretones adding a third just after the hour.

Celta were reduced to 10 men when Alfonso Gonzalez was sent off four minutes from time but an own goal from Moi Gomez was small consolation in the last minute.
